Meanwhile, Spaniard Silvia Soler-Espinosa was tied with former top-10 star
Nadia Petrova 1-1 in the first set when the oft-injured Russian retired on Day
1 and American Shelby Rogers topped Czech Petra Cetkovska 6-0, 6-4.

Also advancing was Austrian Yvonne Meusburger.

This week's top seeds are Australian Open champ Li Na, Agnieszka Radwanska,
U.S. Open runner-up Victoria Azarenka, and French Open runner-up and reigning
Indian Wells titlist Maria Sharapova, who topped 2011 champion and two-time
Indian Wells runner-up Caroline Wozniacki in last year's finale. Sharapova
also won this event in 2006 and was the runner-up to Azarenka in 2012.
